Abstract

Northwest Africa with abundant oil and gas resources,is a hotspot of hydrocarbon exploration for worldwide oil companies,including Chinese ones.Cheliff Basin is just located in the Taylor tectonic belt of the northern Algeria as a Mesozoic petroliferous basin.Because of the multi-episodic orogeny and overprint of complex geological processes in this area,the tectonic evolution of Cheliff Basin is still unclear,which has become a major obstacle to further oil and gas exploration.Based on the tectonic geology and basin dynamics theory,as well as  integrated interpretation of gravity-magnetic date,seismic data and remote sensing images,it is proposed that the Cheliff Basin is a superimposed basin after undergoing the continental margin rifting in Mesozoic and intense compressional inverse in Cenozoic.By applying the theory and methodology of petroleum system,and the seismic interpretation,the favorable zones and exploration targets are evaluated,and the eastern depression and its adjacent tectonic belts (e.g.central low uplift,Tliouanet uplift,Mostanem uplift and Ain Zeft step zone) are pointed out to be the possible target areas for oil and gas exploration.
